Correct Answer: Option B — A composite sailing with a limiting latitude of 51°N will clear the Aleutian Islands.
Bowditch principles for composite sailing dictate that a limiting latitude is chosen to keep the vessel away from high-latitude hazards. By setting a limiting latitude of 51°N, the great circle track is constrained, effectively allowing the vessel to clear the Aleutian Islands while maintaining an efficient route across the Pacific.
